Another of these factors is infertility. Generally, female gorillas mature at 10â12 years of age (or earlier at 7â8 years) and their male counterparts mature more slowly, rarely strong and dominant enough to reproduce before 15â20 years of age.
A herniated disk, sometimes (incorrectly) called a slipped disk, is a common cause of severe back pain and sciatica. A disk in the lumbar area becomes herniated when it ruptures or thins out, and degenerates to the point that the gel within the disk (the nucleus pulposus) pushes outward.
If you suffer from sciatica, you should avoid high-impact exercises that can aggravate your condition. While your feet and knees absorb shock when your foot hits the ground, this shock still radiates up to your lower back. This can further push a slipped spinal disk out of place.
